JULIAN G. NYROP, OF HASTINGS, NEBRASKA.

POLE-ERECTOR.

Specification of Letters Patent.

Application filed April 9, 1919.

To all whom it may concern Be it known that I, JULIAN C. NYRoP, acitizen of the United States, residin at Hastings, in the county of Halland tate of Nebraska, have invented certain new and useful Improvementsin Pole-Erectors, of which the following is a specification.

This invention relates to a device particularly designed for use inerecting telephone, telegraph or analogous poles, and an object of theinvention is to provide a device by means of which telephone, telegraphor analogous poles may be erected, by the utilization of a minimumnumber of men, and also a minimum amount of manual labor, materiallydecreasing the cost of the erection of such poles as well as reducingthe amount of time necessary for such work.

Another object of the invention is to provide a device for erectingtelephone or telegraph poles, which is portable and comprises a bracingsection which is lowered into the hole provided for receiving the buttof a pole, and rests against one side of the said opening for securelybracing the erector structure during the erection of the pole.

A further object of the invention is to provide a pair of spaced angledbracing arms which have a saddle member attached thereto against whichthe butt of a pole engages, during the initial stages of the erecting ofthe pole, the ends of which bracing members engagein the ground upon theopposite side of the hole to that which is engaged by the portion of theerector which extends downwardly into the pole receiving hole.

A still further object of the invention is to provide a Windlassconstruction for raising one end of a pole, to cause the butt end of thelatter to fall into the hole provided for receiving the same whichWindlass structure includes the longitudinally shiftable rotatable shaftwhich when shifted into one position will, upon rotation thereof rotatea Windlass drum for winding a pole raising cable thereon and whenshifted into a different position will rotate a Windlass drum forreceiving the cable thereon to draw the depending portions of the poleerector from the pole retaining hole in the ground.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying Patented Oct. 7,1919.

Referring more particularly to the drawings, wherein like charactersindicate like and corresponding parts throughout the several views, 1indicates the mam axle of the portable pole erector which has supportingwheels 2 rotatably mounted upon the spindle ends thereof.

The supporting structure includes a pair of normally upright bars 3, and4 attached to the axle 1 in any suitable manner such as by U-shapedbolts 5. The lower ends of these supporting bars 3 and 4 have crossbraces 5 connected thereto to which the inner or rear ends of horizontalbraces 6 are connected. A super-structure 7 is carried by the. upper endof the said upright braces 3 and 4 to which super-structure the ends ofthe horizontal portions 8 of the inclined braces 9 are attached. Thesebraces 9 incline downwardly and forwardly from the superstructure 7 andthey have their free lower ends sharpened as shown at 10 for inccivingdrum 15.

sci-lion into the ground during the raising of lhc polc riilfill asindicated at A. to assist in pnwcnting accidental movement of thecrcrtor structure at nllcb times. "lhc, angled braces J arc arcnatc,near the rear ends of tlnii anglcd portions, curring inwardly as clearlyshown at 11 in. Fig. 2 of the drawings, and the saddle 12 which may beconstructod of sheet metal or any analogous material is attached to theinner surfaces of the curved portions 11.

A pair of spaced bearing members 13 are carried by the structure 7 andthey rotatably support a shaft 14 which carries a cable re- The cables16 and 17 are wound about the drum at opposite ends tin-rent and thcyhave their outcr free ends hoolicd to a middle structure 18 adapted tocng'a; -zc liteath i'hc poll: at a point remote from the butt. or cud oithe said pole.

Each of the sections 19 and 20 has a plurality of spurs or spikes22 attached thereto and inclining or curving inwardly as clearly shownin Figs. 7 and S of the drawings, the said spikes or spurs being adaptedto biteinto the wood of the pole A to securely connect the cables 16 and17 to the pole.

The shaft- 11 has a gear 23 mounted thereon which is adapted to meshwith pinion 24 carried by the operating shaft ot' the Windlass structureof thc crcct'or to rotate the shaft 1-1 and consequently the drum 15 bthe rotation of the operating shaft 25. The operating shalt has crankllillltiit: 26 attach-ed to each end thereof and this shaft is slidablysupported by the bearing structures 13 so that it ma be shiftedlongitudinally to move the pinlon 2-1 into or out of mesh withthe gear23 to control the rotation of the shaft 14 and consequently the drum 15during the rotation of the operating shaft 24. A drum27 is slidablysupported, and is rotatably mounted upon the shaft 25, hav- 'ing theclutch section 28 upon one end thereof adapted to mesh with a clutchsection 29 which is keyed to the, operating shaft 24 to rotate the drum27 by the rotation of the shaft 25 when the pinion 21 is out of meshwith the gear 23 as shown in Fig. 5 of the drawings. A latch or lock 30is pivotally connected as shown at 31 to the structure 7 and it isprovided with a recess 32 adapted to engage over the shaft 25, betweenthe clutch sections 28 and 29 when the shaft25 is shifted to move thepinion 24 in mesh with the gear 23 as shown in Fig. 2 ol' the drawin s,to prevent accidental shifting of the she t 25 during its rotation,sufficient to move the clutch sections into operative engagement. Thislatch member 30 is also adapted to engage behind the clutch section 29when the shaft, 2? is shiftcd to move the clutch sectionsv 2B uln 2!)into operative relation and prcwnt shitting longitmlinally or the shaft25 during: the rotation thereof at ouch times, and consequently preventaccidental disconnection bctuccn the shalt 25 and the drum 2?.

A cable 33 is connct-tcd to the drun'i 27 and to the lower end oi" thelongitudinally mow able structure 31 \vl'iicb is adapted to extend intoa hole as indicated at 1? which has been dog to rcccii e the butt of thepole .1. This structure :31, includes a pair oi angled irons 35 and 3 3,which arc connected at their upper and lower ends by suitable angledirons 37 and are braced inlcrnicdiatc their ends by Hlilttlib: bracingmoans 38. The cable Bil in connected to the angle iron 3? at the lowerend 01' such structure. :.o that when the drum 2? is rotatcd for windingtln said cablc thereon, the .trncttnc ll will be aimed up wnrdly out ofthe hole or opening it.

In use; the crcctor structure is pushed to a position udiacent the holeB which has previously been dug at the desired place, and the drum 27 isrotated, through the medium of the shaft 25 for lowering the structure24 into the hole B, in such a position that the said structure willengage against one side of the hole. After this erector has been thuspositioned, the cables 16 and 17 are connected to the pole A, the buttof which has previously been moved in close proximit to or over the holeI3 as shown in Fig. 1 of the drawings, in any suitable manner,preferably by means of the saddle structure 13. After the cables 16 and17 have been connected to the pole A, the shaft 25 is shiftedlongitudinally for moving the pinion 21 into engagement with the ear 23,and consequently moving the clutc1 section 29 out of engagement with theclutch section 28, arrestin rotation of the drum 27 by the 1'0- tation othe shaft 25. \Vhen the pinion 21 meshes with the gear 23, the rotationof the shaft 25 will be imparted to the drum 15, for winding the cables16 and 17 thereon. During the windin of the cables 16 and 17 upon thedrum 15, tie engagement of the butt of the pole A against thesubstantially semicylindrical saddle 12 will prevent the butt end of thepole from raising, and consequent action will be that the ti or outerend of, the pole will be raised 0 the ground and after this tip or outerend has been raised a sufiicient distance, gravit action will cause thepole A to'slide into t 1e hole B, the said pole being guided, to acertain extent, by the saddle structure 12.. During the operation ofraising the pole, any movement of the electors-structure under action orpressure of the pole thcreagainst will be prevented, through the mediumof the structure. 34 which has been lowered into the hole B and thepointedlend :10 ofthe angled bracing 9 will engage into the ground asclearly shown in Fig, 1 ofthe drawings. 7 7

After the vEb tt of the pole A has been lowcred into the opening B theshaft 25 is again shifted, or if it is desired, prior to the saidshifting,the shaftimayehe rotated for unwinding theca'bles 16 efidfromthe drum 15,5 Howeyerathesaeabies may be manually unwounilsif; so;slesired when. the shaft 14 is disconnected frbm the shaft 25. Thus,after'the cables '16 and 17 have been disconne'cted from the pole A andthe shaft 25 has beenshifted to move the clutch 29 into engagement with;the clutch section 28, further rotation ;of the shaft 25 will rotate thedrum-27 raising the structure 24: out of the hole B. Theerector may thenbe moved or baekedawayffrom the pole, and the entire structure orerector'ma be tilted upon the axle 1 as a pivot throng the medium of thestructure 34 to permit the said structure to be moved intoasubstantially horizontal position, transferring the entire weight ofthe erector structurefrom the braces 9 and structure 34 upon the axle 1for facilitatingthe transportation of the erector from one place toanother.
